It wasn't a truvelo, as my understanding is that they don't have a visible flash, and it certainly flashed me. Looked very much like a traditional Gatso - big yellow square box on a grey stand.
Truvelos have a visible flash, but the flash is magenta coloured - not the usual bright white (of gatsos).
Did it look like this?

(truvelos don't have an invisible flash, that's an urban legend - there are several truvelos near me, I have seen them all flash)

On a related note, I've returned the NIP - at what point do I request to see the picture?
Did you accept the conditional offer(s)?
